FIG. 2 is a schematic flowchart of an information transmission method200 according to an embodiment of the application. The informationtransmission method in FIG. 2 may be executed by a terminal device, forexample, the terminal device 20 shown in FIG. 1 . As shown in FIG. 2 , aspecific flow for information transmission includes the followingoperations.

In the operation 210, the terminal device acquires a first sequence.

The first sequence is configured to determine a sequence carryingfeedback information for downlink data.

Specifically, the terminal device may generate different feedbackinformation for different downlink data. Different feedback informationmay be carried in different transmission sequences (called sequences forshort in the embodiment of the application) so as to be sent to anetwork device. The first sequence is equivalently a basic sequence inthese sequences, and all of the other sequences may be determinedaccording to the basic sequence.

The network device may explicitly or implicitly indicate the firstsequence to the terminal device. The operation that the terminal deviceacquires the first sequence includes that: the terminal device receivessequence indication information sent by the network device, the sequenceindication information being used for explicitly or implicitlyindicating the first sequence.

For example, the sequence indication information directly indicates aserial number of the first sequence.

For another example, the operation that the terminal device acquires thefirst sequence includes that: the terminal device receives the sequenceindication information sent by the network device; and the terminaldevice determines the first sequence corresponding to a physicalresource according to the physical resource configured to receive thesequence indication information. That is, the network device implicitlyindicates the first sequence through information such as a resourceposition or size of the physical resource for the sequence indicationinformation.

In the operation 220, the terminal device determines target feedbackinformation for target downlink data according to the target downlinkdata sent by the network device.

The target feedback information may include, for example, at least oneAcknowledgement (ACK) and/or at least one Negative Acknowledgement(NACK).

In the operation 230, the terminal device determines a second sequencecarrying the target feedback information according to the firstsequence.

Specifically, the terminal device, after determining the target feedbackinformation for the target downlink data, may determine the secondsequence corresponding to the target feedback information and configuredto carry the target feedback information according to the firstsequence. Optionally, a serial number of the second sequence may beobtained on the basis of the serial number of the first sequence.

Two manners for determining the second sequence are provided in theembodiments of the application, and will be described belowrespectively.

Manner 1

Optionally, as shown in FIG. 3 , the operation that the terminal devicedetermines the second sequence carrying the target feedback informationaccording to the first sequence, namely the operation 230 in FIG. 2 ,may include operations 231 and 232.

In the operation 231, the terminal device determines other sequencesthan the first sequence from multiple sequences according to the firstsequence, the multiple sequences and multiple types of feedbackinformation meeting a first mapping relationship.

In the operation 232, the terminal device determines the second sequencecorresponding to the target feedback information in the multiplesequences according to the target feedback information and the firstmapping relationship.

The multiple sequences include the second sequence and the firstsequence, and the second sequence may be a sequence the same as thefirst sequence, or may also be another sequence acquired on the basis ofthe first sequence in the multiple sequences.

That is, the terminal device determines the other sequences in themultiple sequences according to the first sequence, the multiplesequences and the multiple types of feedback information meet the firstmapping relationship, the first mapping relationship representscorresponding relationships between the multiple sequences and themultiple types of feedback information, and the correspondingrelationship may be represented by, for example, a table, a formula, animage and the like. That is, the terminal device may search a presettable including the corresponding relationships between the multiplesequences and the multiple types of feedback information to determinethe second sequence corresponding to the target feedback information; orthe terminal device may also calculate an identifier or serial number ofthe second sequence corresponding to the target feedback informationthrough a preset formula and a parameter related to the target feedbackinformation. There are no limits made thereto in the application. Theterminal device may determine the second sequence corresponding to thetarget feedback information according to the target feedback informationfor the target downlink data and the first mapping relationship.

In the embodiment, the terminal device determines the multiple sequencesin advance so as to directly select the sequence configured to carry thetarget feedback information in the multiple sequences according to thetarget feedback information during subsequent transmission, and is notrequired to calculate the sequence every time.

Optionally, the first mapping relationship may be configured for theterminal device by the network device. Before the terminal devicedetermines the other sequences than the first sequence in the multiplesequences according to the first sequence, the terminal device receivessecond configuration information sent by the network device, the secondconfiguration information including the first mapping relationship. Or,the first mapping relationship is predefined by the terminal device andthe network device, for example, specified in a protocol.

Optionally, the number of multiple sequences is determined according toa transmission parameter, and the transmission parameter includes anyone of: the number of a TB in the target downlink data; the number of acode block group in the target downlink data; a product of the number ofthe TB and the number of the code block group in the target downlinkdata; and a maximum bit number of the target feedback information.

Optionally, before the operation that the terminal device determines theother sequences than the first sequence in the multiple sequencesaccording to the first sequence, the method further includes that: theterminal device receives the transmission parameter sent by the networkdevice.

Optionally, if a value of the transmission parameter is n, the number ofthe multiple sequences may be 2^(n), n being a positive integer.

For example, if the transmission parameter is the number of the TB inthe target downlink data and the number of the TB is n=1, there are twosequences configured to carry the feedback information, one beingconfigured to carry an ACK and the other being configured to carry aNACK; and if the number of the TB is n=2, there are 2²=4 sequencesconfigured to carry the feedback information, and the 4 sequences areconfigured to carry an ACK and an ACK, an ACK and a NACK (the ACK istransmitted before the NACK), a NACK and an ACK (the NACK is transmittedbefore the ACK), and a NACK and a NACK respectively.

Each sequence in the multiple sequences corresponds to an offset value,and a difference between a serial number of each sequence and the serialnumber of the first sequence is the offset value corresponding to theeach sequence. For example, the serial number of each sequence in theother sequences than the first sequence in the multiple sequences isequal to a sum of the serial number of the first sequence and the offsetvalue corresponding to the each sequence. Optionally, these sequenceswith different serial numbers may be a series of sequences generated bycyclic shift of the basic sequence.

Optionally, before the operation that the terminal device determines theother sequences than the first sequence in the multiple sequencesaccording to the first sequence, the method further includes that: theterminal device receives first configuration information sent by thenetwork device, the first configuration information including the offsetvalue corresponding to each sequence. Or, the offset value is predefinedby the terminal device and the network device, for example, specified ina protocol.

For example, according to the first mapping relationship shown in Table1, if the number of the TB in the target downlink data is n=1, the totalnumber of the sequences is 2. Table 1 shows the first mappingrelationship in case of n=1. When the feedback information includes anACK, the feedback information is carried in a sequence S_(i); and whenthe feedback information includes a NACK, the feedback information iscarried in a sequence S_(i)+Δ_(offset,0).

TABLE 1 Resource serial number of Feedback information transmissionsequence ACK S_(i) NACK S_(i) + Δ_(offset,0)

The terminal device, after receiving the sequence indication informationsent by the network device, acquires the serial number S_(i) of thefirst sequence and the number n=1 of the TBs carried in the targetdownlink data. The terminal device determines the multiple sequencesaccording to the first sequence and the offset value corresponding toeach sequence in the multiple sequences in Table 1. The terminal devicedecodes the TBs, determines a target feedback result for the targetdownlink data and determines the sequence corresponding to the targetfeedback result and configured to carry the target feedback result inthe multiple sequences according to the first mapping relationship shownin Table 1. If the target feedback result includes an ACK, the terminaldevice sends the sequence S_(i) to the network device; and if the targetfeedback result includes a NACK, the terminal device sends the sequenceS_(i)+Δ_(offset,0) to the network device, the offset value Δ_(offset,0)being, for example, 1.

For another example, according to the first mapping relationship shownin Table 2, if the maximum bit number of the target feedback informationis n=2, the total number of the sequences is 4. Table 2 shows the firstmapping relationship in case of n=2. When the feedback informationincludes an ACK and an ACK, the feedback information is carried in thesequence S_(i); when the feedback information includes an ACK and aNACK, the feedback information is carried in the sequenceS_(i)+Δ_(offset,0); when the feedback information includes a NACK and anNACK, the feedback information is carried in a sequenceS_(i)+Δ_(offset,1); and when the feedback information includes a NACKand a NACK, the feedback information is carried in a sequenceS_(i)+Δ_(offset,2).

TABLE 2 Resource serial number of Feedback information transmissionsequence ACK, ACK S_(i) ACK, NACK S_(i) + Δ_(offset,0) NACK, ACK S_(i) +Δ_(offset,1) NACK, NACK S_(i) + Δ_(offset,2)

The terminal device, after receiving the sequence indication informationsent by the network device, acquires the serial number S_(i) of thefirst sequence. The terminal device determines the multiple sequencesaccording to the first sequence and the offset value corresponding toeach sequence in the multiple sequences in Table 2. The terminal devicedetermines the target feedback result for the target downlink data anddetermines the sequence corresponding to the target feedback result andconfigured to carry the target feedback result in the multiple sequencesaccording to the first mapping relationship shown in Table 2. If thefeedback result includes an ACK and an ACK, the terminal device sendsthe sequence S_(i) to the network device; if the feedback resultincludes an ACK and a NACK, the terminal device sends the sequenceS_(i)+Δ_(offset,0) to the network device; if the feedback resultincludes a NACK and an ACK, the terminal device sends the sequenceS_(i)+Δ_(offset,1) to the network device; and if the feedback resultincludes a NACK and a NACK, the terminal device sends the sequenceS_(i)+Δ_(offset,2) to the network device. The offset values may beΔ_(offset,0)=1, Δ_(offset,1)=2 and Δ_(offset,2)=3.

Manner 2

Optionally, as shown in FIG. 4 , the operation that the terminal devicedetermines the second sequence carrying the target feedback informationaccording to the first sequence, namely the operation 230 in FIG. 2 mayinclude operations 233 and 234.

In the operation 233, the terminal device determines a target offsetvalue corresponding to the target feedback information from multipleoffset values according to the target feedback information and a secondmapping relationship, the second mapping relationship representingcorresponding relationships between the multiple offset values and themultiple types of feedback information.

In the operation 234, the terminal device determines the second sequenceaccording to the first sequence and the target offset value.

The second sequence may be a sequence the same as the first sequence(the target offset value is 0), or may also be another sequence acquiredon the basis of a respectively corresponding offset value and the firstsequence.

That is, the terminal device may determine the target offset valuecorresponding to the target feedback information in the multiple offsetvalues at first according to the target feedback information and thesecond mapping relationship. The second mapping relationship representsthe corresponding relationships between the multiple offset values andthe multiple types of feedback information, and the correspondingrelationship may be represented by, for example, a table, a formula, animage and the like. That is, the terminal device may search a presettable including the corresponding relationships between the multipleoffset values and the multiple types of feedback information todetermine the target offset value corresponding to the target feedbackinformation; or the terminal device may also calculate the target offsetvalue corresponding to the target feedback information through a presetformula and a parameter related to the target feedback information.There are no limits made thereto in the application. Secondly, theterminal device determines the second sequence carrying the targetfeedback information according to the first sequence and the targetoffset value. For example, the serial number of the second sequence isequal to a sum of the serial number of the first sequence and the targetoffset value.

In the embodiment, the terminal device determines the offset valuecorresponding to the target feedback information so as to directlycalculate the sequence configured to carry the target feedbackinformation according to the first sequence and the offset value, and isnot required to determine the multiple sequences in advance in the firstmanner.

Optionally, the number of the multiple offset values is determinedaccording to a transmission parameter, and the transmission parameterincludes any one of: the number of the TB in the target downlink data;the number of the code block group in the target downlink data; theproduct of the number of the TB and the number of the code block groupin the target downlink data; and the maximum bit number of the targetfeedback information.

Optionally, if a value of the transmission parameter is n, the number ofmultiple offset values may be 2^(n), n being a positive integer.

Optionally, before the terminal device determines the multiple offsetvalues, the method further includes that: the terminal device receivesthe transmission parameter sent by the network device.

Optionally, before the operation that the terminal device determines thetarget offset value corresponding to the target feedback information inthe multiple offset values according to the target feedback informationand the second mapping relationship, the method further includes that:the terminal device receives third configuration information sent by thenetwork device, the third configuration information including the secondmapping relationship.

Optionally, the second mapping relationship is predefined by theterminal device and the network device, for example, specified in aprotocol.

For example, according to the second mapping relationship shown in Table3, if the number of the TB in the target downlink data is n=1, thenumber of the offset values is 2. Table 3 shows the second mappingrelationship in case of n=1. When the feedback information includes anACK, the offset value is Δ_(offset,0); and when the feedback informationincludes a NACK, the offset value is Δ_(offset,1).

TABLE 3 Feedback information Offset value ACK Δ_(offset,0) NACKΔ_(offset,1)

The terminal device, after receiving the sequence indication informationsent by the network device, acquires the serial number S_(i) of thefirst sequence and the number n=1 of the TBs carried in the targetdownlink data. The terminal device decodes the TBs, determines thetarget feedback result for the target downlink data and determines thetarget offset value corresponding to the target feedback resultaccording to the second mapping relationship shown in Table 3. If thetarget feedback result includes an ACK, the corresponding target offsetvalue is Δ_(offset,0); and if the target feedback result includes aNACK, the corresponding target offset value is Δ_(offset,1). Forexample, the offset value Δ_(offset,0) may be 0 and Δ_(offset,1) maybe 1. Then, the terminal device adds the serial number of the firstsequence to the target offset value to obtain the serial number of thesecond sequence carrying the target feedback result, and sends thesecond sequence to the network device.

For another example, according to the second mapping relationship shownin Table 4, if the maximum bit number of the target feedback informationis n=2, the number of the offset values is 4. Table 4 shows the secondmapping relationship in case of n=2. When the feedback informationincludes an ACK and an ACK, the offset value is Δ_(offset,0); when thefeedback information includes an ACK and a NACK, the offset value isΔ_(offset,1); when the feedback information includes a NACK and an ACK,the offset value is Δ_(offset,2); and when the feedback informationincludes a NACK and a NACK, the offset value is Δ_(offset,3).

TABLE 4 Feedback information Offset value ACK, ACK Δ_(offset,0) ACK,NACK Δ_(offset,1) NACK, ACK Δ_(offset,2) NACK, NACK Δ_(offset,3)

The terminal device, after receiving the sequence indication informationsent by the network device, acquires the serial number S_(i) of thefirst sequence. The terminal device determines the target feedbackresult for the target downlink data and determines the target offsetvalue corresponding to the target feedback result according to thesecond mapping relationship shown in Table 4. If the target feedbackresult includes an ACK and an ACK, the corresponding target offset valueis Δ_(offset,0); if the target feedback result includes an ACK and aNACK, the corresponding target offset value is Δ_(offset,1); if thefeedback result includes a NACK and an ACK, the corresponding targetoffset value is Δ_(offset,2); and if the feedback result includes a NACKand a NACK, the corresponding target offset value is Δ_(offset,3). Theoffset values may be Δ_(offset,0)=0, Δ_(offset,1)=1, Δ_(offset,2)=2 andΔ_(offset,3=3). Then, the terminal device adds the serial number of thefirst sequence to the target offset value to obtain the serial number ofthe second sequence carrying the target feedback result, and sends thesecond sequence to the network device.

In 240, the terminal device sends the second sequence to the networkdevice.
